About the Scroll dial PCB

Scroll dial is an open source Nordic nRF PCB design by maker-lukas, published on GitHub. It is a 2-layer board measuring 20 × 44.7 mm, with 12 components from 11 distinct parts.

Its main chip is the XIAO-NRF52840-DIP, from the Nordic nRF family. Other key parts include the XIAO-NRF52840-SMD. By type, the board carries 4 resistors, 3 connectors, 2 ICs, 2 capacitors and 1 switch.

It belongs with the keyboards, sensors and iot & wireless designs in this gallery.

Scroll dial: common questions

What microcontroller does the Scroll dial use?

The Scroll dial is built around the XIAO-NRF52840-DIP, from the Nordic nRF family.

How big is the Scroll dial PCB?

The Scroll dial measures 20 × 44.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Scroll dial?

12 components, from 11 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Scroll dial design files?

From the maker-lukas/Scroll-Dial repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Scroll dial design in my own project?

The repository has no license, so all rights stay with maker-lukas. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Scroll dial without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Nordic nRF firmware against it before you order a PCB.
